She jokingly mentioned she's in a relationship. Do I abort or proceed?

[Creativemindreader]

I'm taking a new marketing training and I met this girl in my class taking the same course. She's smart, I'd say an 8/10, I know she's really attracted to me.
I was going to ask her out this weekend but yesterday we were just playfighting in class, it got really intense and midway she instantly said she's in a relationship jokingly.

What does she mean by this? Although i kind of laughed it off.
But she messaged me later in the day asking about my day.. I haven't responded up until now which is unlike me.

Just ask her. Don't pvssyfoot around it.

short answer because you have no concept of seduction or game... abort.

She was just having fun with you and then realized you may think she's into you, but she's not and she let you know so you don't have any false expectations.

You're friendzoned...
